This class provides a place to set additional or token-level data for
asynchronous RPC operations. It also allows an IResponder to be attached
for an individual call.
The AsyncToken can be referenced in
ResultEvent
and
FaultEvent
from the
token
property.
message:IMessage
[read-only]
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Provides access to the associated message.
Implementation public function get message():IMessage
responders:Array
[read-only]
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
An array of IResponder handlers that will be called when
the asynchronous request completes.
Eaxh responder assigned to the token will have its result
or fault
function called passing in the
matching event before the operation or service dispatches the
event itself.
A developer can prevent the service from subsequently dispatching the
event by calling event.preventDefault()
.
Note that this will not prevent the service or operation's
result
property from being assigned.
Implementation public function get responders():Array
result:Object
[read-only]
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
The result that was returned by the associated RPC call.
Once the result property on the token has been assigned
it will be strictly equal to the result property on the associated
ResultEvent.
This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange
event.
Implementation public function get result():Object
public function AsyncToken(message:IMessage = null)
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Constructs an instance of the token with the specified message.
Parameters | message:IMessage (default = null ) — The message with which the token is associated.
|
public function addResponder(responder:IResponder):void
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Adds a responder to an Array of responders.
The object assigned to the responder parameter must implement
mx.rpc.IResponder
.
Parameters
| responder:IResponder — A handler which will be called when the asynchronous request completes.
|

public function hasResponder():Boolean
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Determines if this token has at least one mx.rpc.IResponder
registered.
Returns | Boolean — true if at least one responder has been added to this token.
|
Event Object Type: mx.events.PropertyChangeEvent
property PropertyChangeEvent.type = mx.events.PropertyChangeEvent.PROPERTY_CHANGE
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Dispatched when a property of the channel set changes.
The
PropertyChangeEvent.PROPERTY_CHANGE
constant defines the value of the
type
property of the event object for a
PropertyChange
event.
The properties of the event object have the following values:
Property | Value |
---|
bubbles | Determined by the constructor; defaults to false. |
cancelable | Determined by the constructor; defaults to false. |
kind | The kind of change; PropertyChangeEventKind.UPDATE
or PropertyChangeEventKind.DELETE. |
oldValue | The original property value. |
newValue | The new property value, if any. |
property | The property that changed. |
source | The object that contains the property that changed. |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget . |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
